LOADING ATTACHMENT FOR CABLEWAYS.

- Specification of Letters Patent.

Patented Nov. 19, 1918..

Application filed April 28, 1917. Serial No. 165,064.

To all whom it may concern:

Be it known that I, AUGUST DANIELSON, a citizen of the .United States, residing at Everett, in the county of Snohomish and State-of Washington,"have invented a new 1 and useful Improvement in Loading Attachments for Cableways, of which the following is a specification. 1

This invention relates to cableways, particularly to such as are used for logging, although the invention may be applied to the handling of other objects than" logs. The invention consists of a device to be used in connection with cableways designed to facilitate the loading of the logs upon cars. It is, therefore, called a loading attachment for cableways.

The object of this invention is to provide a mechanism which may be employed in connection with logging cableways, whereby the transfer of logs from the cableway to the car may be secured more expeditiously and conveniently.

The invention comprises the parts and combinations of parts which will be hereinafter described and then particularly pointed out in the claims concluding the description. The accompanying drawings show the device applied in the preferredmanner.

Figure 1 is an elevation showing the head mast and the delivering and loading end of a logging cableway having theinvention applied thereto.

Fig. 2 is a plan view of the same.

It is the custom in operating cableways for logging, to establish a head mast or tree from which the cableway extends and about which the cableway is moved as the logging progresses. In consequence, the operation of the cableway for any one setting covers a segment of acircle having its center at the head tree. Its outer end is moved in succession from one segment to the next, as the logging progresses.

The railroad, over which the logs are to be conveyed is intended to run alongside the head tree. The present invention is designed to facilitate the loading of the logs upon the cars and to overcome the difliculties which would otherwise accompany this work due to the changing position of the cableway.

The main cableway is indicated at 2. Upon this is placed a carriage 20, which travels back and forth with the logs. The fall-line rope, or the line which is used to attach to the logs in bringing them in, is

ported in elevated position from a head tree or mast 1. This cableway, and-the means for operating it, are, or may be, of any suitableconstruction.. As my invention does not reside in this part of the apparatus, I have not illustrated the same in detail and will not attempt further description thereof.

In conjunction with the main cableway, a loading cableway is employed. Thisloading cableway employs a trackway cable 3 which extends from an elevated support on the head mast and thence to an anchorage, as 31, located at some distance from the head mast and fairly close to the line of the main cableway. This causes the loading cableway to extend in the same general direction, and preferably slightly to one side, of the main cableway, as is indicated in Fig. 2.

As the logs are brought in by the main cableway, they are dropped anywhere within the range of action of the loading cableway 3. This may possibly be at some distance from the head mast. The two cableways extending substantially in the same direction from the head mast, the supplemental, or loading cableway, may pick up the log and bring it along to the loading position. As, however, the cableway is shifted in its angular direction from the head mast it will, throughout at least one-half of its positions, extend away from the track. The position of the track relative to the head mast is shown in Fig. 2. The track 80 is the main line upon which the cars being loaded stand. The car upon which the engine and the operating mechanism for the cableway rest is shown at 9. In some cases the operating engine will be mountedupon a skid instead of upon a car. In either case it will be located close tothe base of the head tree.

In the position of the maincableway 2 and the loading cableway 3, as shown in Fig. 2, it would not be possible to load cars standing upon the main line track 80, using these cableways alone. This condition would exist in all positions of the cableway excepting those in which it extends across and over the loading track. It is for the purpose of obviating this difliculty and to make it possible l ll) the line 4sextending to and through a sheave 40, supported from the cable 8, and thence back to a connection to the carriage 30, While the line &1 extends from the carriage over a suitable support'or sheave carried by the head tree and thence to the drum, by: which' 'it" is handled; A pick-up'1ine42'ex tends from the engine over a sheave 45 carried by the head tree and thence over a sheave 44; carried by the carriage30, and thence either to a direct, connection to the load, or about a suitable sheave, or "sheaves,

- 43, by which the load liftingcapacity is in track,is a guy-line 5. Secured upon'or' from this guy-line, a line sheave 50, through which passes atransfer line 6. This line extendsfrom the engine,over a sheave 53,- carried by the head tree, thence over the sheave I 50, whichis carried by the line 5, at an elevated position and at a position beyond the loading track. This transfer line is then led, in any suitable or desired manner, back to the mechanism which the logis picked up'by the line 42. As herein shown, this this sheave a sufficient distance from the linefirst extends over :a sheave 52, carried by the guy-line 5, out farther toward its outer end, thence over'sheave 51 carried nearer to its inner endand thence to the load-Ilifting device. i

When-a loghasbeen brought by the load ing line in to-a position adjacent to the head tree and is thus suspendedin elevated pos1-- tion, the transfer line 6 is hauled in by its drum and the pick-up line 42 is, at the'sa ne time,allowed topay out. In consequence, the log is transferred laterally of the. sup

plemental or loading cableway'-3, until it is brought into position I over the car. The

transfer line then acts'as a carryingor sup porting line for the log. If it is. vpaid out and at the same time the pick-up'line is cor-' respondingly paid out, the log will be lowered upon the car. The position of the log at this time will be determined by the manner ofh'andling these two lines.- It Is thus possible to drop the log at any point between theposition of the carriage 30 and the position of the sheave 50. By locating head tree 1, the log-may be loaded upon one of several lines of track. I

Copies of this patent may be obtain edfor The guy-line 5, upon which the transfer line is mounted, need not be shifted in posi tion, except possibly once during the handling of the entire tract of timber; A single position of the transfer line is capable ,offhandling the logs brought in by the cable waywliile""'shifting through a large sector. vBy the use of this device, loading of the logs is greatly facilitated. It is not necessary to shift the track to correspond to the shift ingof the main cableway. What I laim as my invention is 1. A loghandlingapparatus comprising a head mast, a mainor hauling cableway'extending from said mast and provided with: means for bringing 2m logs, a loading cable-r way extending from the same mast 1n sub stantially the same direction as the main cableway and provided with means for bringingc'in logs,a guyline extending-froin the same mast in a direction diverging from that of the cableways, a guidesheave'carriedin' elevated position by said guy line and'a transfer line extending through'said sheave and: connecting with, a load-supporting member of the loading cableway.

20A log handling apparatus comprising a head mast, a main or hauling cableway extending from said mastiand provided with means for bringing in logs, said means including a haul-back line and a distant guide sheave for the haul-back line carried :by the trackway'cable, a loading cableway extending from the same mast in; substantially the same direction 'asthemain cableway and provided with :means for bringing inJlogs, a guy line extending from: the same mast in a:

direction diverging. fromithatof the cableways, a guidesheave carried in elevated position by said guy line and a transfer line.
